In England, 3 people have been arrested over the murder of a man in Leicester - which could be linked to a suspected arson attack that killed the wife and 3 teenage children of a Dublin based doctor.
Muhammad Taufiq al-Sattar is a consultant neurosurgeon who works at a number of hospitals in Dublin.
His wife and 3 children were found dead after a house fire at their home in Leicester.
Those being held include two 19 year old women and a man, also 19, who was arrested in London.
The victim - who was found beaten on the street on Thursday night - has yet to be formally identified.
Detectives are trying to establish if the house fire nearby could've been a revenge attack.
